' To all whom it may concern:

" STORAGE BATTERY.

- Be it known that I, HERMAN HENRY KEMPF, a citizen of the United States of America, and a resident of the borough of Brooklymfiin the'city of New York, county of Kings, and State of New York, hate invented certain new and useful Improvements in Storage Batteries, of which the following is a'specification.

This invention relatesto the combination with a storage battery of an electric meter by which the strength of the battery may 4 be ascertained'without lieing to the necesto the casing.

sity offattaching a meter separate there from, only the depression of a key being required to throw the current into. the meter and-show the reading.

The object of the invention is to soarrange the means of attachment and connections that the meter may be secured to the inclosing casing of the battery after the battery has been made complete in other respects including the pouring in of the sealing compound, whereby the compound may be allowed to cool off before attaching the meter-so that the meter will not be injured by the heat. 5 L

Further objects relate to the arrangement of electrical connections so that they are properly completed upon securing the meter Further objects relate to the provision of a shunt and connectionswhereby this is connectedinto the battery circuit so as to put the battery under load when a reading is to be taken as the reading will then become indicative of the degree of charge. remaining-in the battery.

In the accompanying sheet of drawings which forms a part ofthis application-'- Figure 1 is a perspective of a storage battery embodying my invention. Fig. 2 is a vertical section showing the upper part of the battery, the means of'attachment for the electric meter, the shunt and connections.

Three battery cells A AA are shown inclosed in a casing B. The top of the casing is an insulating plate 0 through which the positive and negative terminals E and F of the cells project. Sealing compound G, as-wax, is melted and poured onto thecells,

filling the space between the tops of the cells and'the underside of the cover plate. Threaded sockets H and K are secured'to the cover plate and one is electrically con- Speeification of Letters Patent. Application filedMay 1a, 19 1o. Serial No. 561,216"

other to the other 'cell terminal by wires L L which leadunder the cover plate.

A voltmeter M in a suitable metal frame is secured to the sockets in the cover plate by screws N N, at one screw and socket insulation 0 being interposed. It is not essential, however, that the meter frame be en-. tirely of metal, and if it is of hard rubber this .special insulation isunnecessary. In this case the electrical connections will lead nected to one of the cell terminals and the? to the points of attachment in the, case of x The electrical connectionsor terminals of the meter are one P to the the amount carried, however, depending upon'the size of the battery. The terminals of this resistance are connected to the same points as the terminals of the meter so that upon closure of the switch this resistance will also be connected to the battery terminals and the battery put underload so\ that the voltage will fall to a point indicative of the charge.

What I claim as new, and desire to secure by Letters Patent of the United States,,is

1. The combination ina storage battery having positive and negative terminals, of an inclosingcasing with an insulating plate, a pair of threaded sockets secured to the plate, one being connected with the positive and the other to the negative terminal,

an electric meter the frame of which is adapted to be secured to thesockets by suitable securing means with interposed insulation between the frame and one of the sockets with its securing means, electrical connections from the meter to the securing means, and a normally open sprin switch interposed in the connections,substantially as described.

2. The combination ina storage battery 1m,-pne being -connec ted to the havin positiveiand negative terminals, of

mine osing-caslng with an insulating plate,

a; pgirgef thi'eaded sockets. secured to the ,e e sitive and-the fother tothe negative termmhl, an

electric-meter the frame of which is adapted .t'o secured to thesockets by suitable securing means with insulation betweenthe frame I and oneflofthe sockets with its securing means, 0; Tesistance connected in parallel with the metel electrical connections between o ne terminal of the meter and one termmel oi the reslstance, and one termmal otithe' kist tery, espr ing switch connected to tially as described,
